IMPROVEMENT IN H EATI NG-STOVES.

Specificatiou forming part of Letters Patent No. 44.208, dated September13, 1864.

To all whom it may concern:

Be it known that 1, JAMES L. W1LLsoN, of Chicago, in the county of Cookand State of Illinois, have invented a new and useful Improvement inStoves; and I do hereby declare that the following is a full and exactdescription thereof, reference being bad to the accompanying drawings,and to the letters of reference marked thereon.

The nature of my invention consists in providing a stove with air,heat-chambers, and flues, constructed, arranged, and operating in themanner hereinafter described.

To enable others skilled in the art of constructing stoves, I willproceed to describe its construction and operation.

In the accompanying drawings, Figure l is a perspective view of myimproved stove. Fig. 2 represents asectional view of the same through orat the point indicated by the line marked 1. (See Fig. 1.) Fig. 3represents a sectional view through or at the point indicated by theline marked 2. (See Fig. 1.)

In the accompanying drawings, A represents the fire-box of the stove.

B represents the pipe or flue, which, with its branches g and h,connects the tire-box A with the heat chambers E and O, which are alsoconnected with each other by means of two hollow columns, (marked D.)The heatchamber 0 is surrounded by an air-chamber, (marked 00,) intowhich is admitted cold air through the openings marked 3.

m represents the tire-door, and i the register of the fire-box A.

f represents openin gs or registers connected with the air chamber 00.

7 represents an elbow for connecting the pipe B with the heat-chamber O.

n represents a valve placed in the pipe or flue B between the branches 9and h.

I propose making the heat-chamber 0, columns D, and pipe B of sheetiron, and the balance of the stove of cast-iron; but it will be readilyobserved that the entire stove can be, if desired, made of either castor sheet lIOIl. The form, size, and manner of constructing the variousparts of my improved stove I leave to the skill and good judgment of themeehanic skilled in the art of constructing stoves.

The operation of my improvement is as follows: Having all thingsconstructed and arranged as herein described and represented,

I make a fire in the fire-box A, and after it has sufficiently kindledso as to burn without making much smoke, I then turn the valve in theposition represented by the dotted lines 8, which will cause the heat(indicated by arrows marked 4) to pass up and through the branch 9 intopipe B and down it into the heatchamber 0, and from it up through thecolumns D into the heat-chamber E, and from it the heat finallypasses'out through the branch IL into the pipe B, and from it into theflue or chimney. The cold air (represented by arrows marked 5) entersthe air-chamber w through openings 3, and becomes heated and passes out,as indicated by arrow-points marked 6, through the openings orregistersf; or the heated air in the chamber 00 may be made to pass intothe columns D, as shown by the arrows marked 9.

The advantages of my improvement are as follows: first, economy'in fuel,by retaining and causing the heat to pass through and traverse thevarious flues and chambers herein described and represented; second, incansing the heat to be thrown down and through the bottom part of thestove, thereby making the lower part of the stove the hottest part,which is a very desirable thing for ladies, who are compelled, when theydesire to warm their feet at the stoves now in common use, to raisetheir feet to an elevation which is not, to them, at all desirable, orelse go with cold feet, which is a very prolific source of disease;third, by my improvement the heat of the stove is brought in contactwith the coldest air in the room, which is always next to the floor.

Having thus. described the nature, construction, operation, andadvantages of my improvement in stoves, what I claim as of my inventionis- 1. The arrangement of the fire-box A, pipe B, branches 9 and h,valve n, heat-chambers O and E, columns D, cold-air chamber 00, withopenings 3 andf, the Whole being constructed, arranged, and operatingsubstantially as herein described, and for the purpose set forth.

2. Placing under the fire-box of stoves a heatchamber, surrounded by acold-air chamber, said heat-chamber being connected with a flue or fiuesand the lire-box of the stove, as herein described, and for the purposeset forth.
